Significant Improvement and Mechanism of Ultrasonic Inactivation to <i>Escherichia coli</i> with Piezoelectric Effect of Hydrothermally Synthesized <i>t</i>-BaTiO₃

Piezoelectric effect was first used for disinfection. In this process, hydrothermally synthesized nano/micrometer tetragonal-BaTiO3 was selected as the piezo-catalyst which was stressed by ultrasound to generate piezoelectric potential. It was found that the inactivation number of the nano/micromete... View More
